What are the advantages of CCD visual inspection equipment?

CCD visual inspection has become a comprehensive technology integrating optics, electronics, precision machinery and computer technology. In fact, CCD can be used almost wherever film and photoelectric inspection technology are available.

CCD can be called a CCD image sensor. CCD is a semiconductor device that can convert optical images into digital signals. CCD vision is commonly understood as a camera equipped with a CCD chip. This kind of camera is used in industrial production to form a set of equipment with detection functions, which is called CCD vision detection equipment.

CCD visual inspection equipment relies on CCD imaging cameras and inspection systems. The inspection system is important. The inspection system is based on the customer's product inspection requirements. The system development engineer will then develop the system according to the customer's requirements. Note: There are general detection systems in the industry. These systems are generally developed in advance and may integrate most of the detection functions. If you can meet the requirements, you can purchase it directly and integrate it with the hardware.

The advantages of CCD visual inspection mainly include the following five points:

1. High quantum power

This is the advantage. The average quantum power is 30% to 50%, and can reach up to 90%, which is about 100 times that of ordinary photographic films.

2. Wide spectral response range

The spectral response range of CCD is 400~1100nm, which is much extended to the near-infrared band than the sensitive band range of general photographic emulsions (350~700nm).

3. Good linearity

The imaging intensity is proportional to the incident light flux and has an excellent linear relationship.

4. Wide dynamic range

The CCD dynamic scale refers to the magnitude difference between the darkest stars and the brightest stars that can be explored. The dynamic range of CCD can reach 105, which is far better than that of film.

5. High resolution ability

The smaller the pixel standard, the higher the resolution. The pixel size of the CCD currently produced is 9-25 μm, which is consistent with the resolution ability of fine-grained films.
